AVAudio change with UILabel

[narconate]

Hi im working on an app at the moment and not sure how to do this but I would like a UIButton to play an audio file - but for the Audio file to be different depending on what a UILabel displays.
I have one UILabel and several UIButtons - when the UIButton is pressed it changes the text of the UILabel - i would like to create another UIButton that will play the audio file that says "this is red" when the text in the UILabel shows the text "red".Its an app im working on for hearing impaired

I appreciate any help that can be given

Still spending long hours trying to work out whats wrong here:
I have input the following code, and attached it to a button in the interface:

- (IBAction)wordsoundbutton:(id)sender {
    if (wordlabel.text == @"red") {
        NSString *path = [[NSBundle mainBundle]pathForResource:@"test" ofType:@"mp3"];
        AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath: path] error:NULL];
        theAudio.delegate = self;
        [theAudio play];
        
    }
}

When i click the button when the UILabel says "red" it comes up with the following message:
